| 英文摘要 | Hypocrellin B (HB), a natural pigment, when adsorbed on colloidal TiO2 can participate in the sensitization process by injecting electrons from its excited singlet and triplet states into the conduction band of the semiconductor. Upon excitation in its absorption band, 80% of the fluorescence emission of HB could be quenched by colloidal TiO2. Lifetime measurements and time-resolved absorption spectra gave the rate constant for the electron injection process from the excited singlet and triplet states of HE into the conduction band of the semiconductor as 6 x 10(8) and 1.3 x 10(6) s(-1), respectively. Analysis of the electron paramagnetic resonance spectra confirmed the generation of the cation radical of HE. (C) 2000 Elsevier Science B.V. All rights reserved. |
